Abstract

A process for the electrolytic coloring of aluminum or aluminum alloys consisting of subjecting the previously anodized piece to two electrolytic treatments in a coloring solution (solution of soluble metal salts). The first consists of an alternating current treatment with an elevated positive polarization, to cause a modification in the pores of the anodic layer. After this electrolytic treatment and in the same bath, the sample is colored by applying thereto an alternating current. The electrolytic treatment prior to coloring permits colors differing from those produced in conventional coloring to be obtained.
